Lock

LOCK, 1. an analytical moment in which the perceptics of the engram are approximated, thus restimulating the engram or bringing it into action, the present time perceptics being erroneously interpreted by the reactive mind to mean that the same condition which produced physical pain once before is now again at hand. Locks contain mainly perceptics; no physical pain and very little misemotion. (SOS, p. 112) 2. a situation of mental anguish. It depends for its force on the engram to which it is appended. The lock is more or less known to the analyzer. It’s a moment of severe restimulation of an engram. (EOS, p. 84) 3. those parts of the time track which contain moments the pc assoc~ates with key-ins. (HCOB 15 May 63) 4. conscious level experiences which sort of stick and the individual doesn’t quite know why. (SH Spec 72, 6607C28)
